Warehouse & Supply Chain Systems That Deliver On-Time Performance.
Manhattan PKMS and WMS initiatives fail not because the platform lacks capability, but because implementations are designed around standard warehouse processes instead of your real-world operations. Your inventory workflows, RF gun processes, carrier compliance requirements, labor productivity models, and host system integrations require a solution tailored to your environment. SourceMash provides AS400 PKMS Implementation & Support Services that bridge both sides of the operation Manhattan PKMS and IBM i (AS400) platforms. We help organizations modernize and extend mission-critical RPG, COBOL, and CL applications, optimize warehouse execution, and integrate legacy and modern systems without the risk and disruption of a full platform rewrite.
Solution Area 01
Manhattan WMS Implementation & Configuration
A successful Manhattan WMS implementation starts with understanding how your warehouse actually operates—not how a standard software template assumes it should. SourceMash takes an operations-first approach, mapping your inbound, putaway, replenishment, picking, packing, and shipping workflows before configuring a single rule, template, or process.
Our team delivers end-to-end Manhattan WMS implementations aligned to your SKU profiles, labor models, carrier requirements, RF workflows, and host system integrations. The result is a warehouse platform designed around real operational performance, scalability, and long-term maintainability.
Configure ASN-based receiving, PO-based receiving, directed putaway, cross-docking workflows, vendor compliance controls, and warehouse inspection processes to improve inbound accuracy and throughput.
Optimize warehouse execution through zone picking, batch picking, cluster picking, pick-and-pass strategies, RF-directed workflows, and advanced wave management aligned with service-level commitments.
Deploy streamlined packing, manifesting, carrier labeling, parcel sorting, trailer loading, and outbound EDI processes that accelerate shipment execution and improve carrier compliance.
Improve warehouse productivity with velocity-based slotting, optimized pick paths, golden-zone utilization, seasonal re-slotting strategies, and automated slotting recommendations.
Implement Manhattan Labor Management capabilities including engineered labor standards, productivity tracking, associate performance dashboards, and incentive program support.
Configure replenishment automation, cycle counting, inventory accuracy controls, location-based management, and LPN tracking to maintain inventory integrity across the facility.
